I hadn't noticed before! I guess it's the last of the chin pad tanks, as it's a 2003 bike. I quite like the way it looks, slightly less "bunched up" at the front.
@footgoose The exhaust hangers (and the cans) were custom made by a shop in the UK, which is why I couldn't tell what they were. I went back through the paperwork and found a receipt from Long Life Exhausts, in Bristol.

Aha, thanks for clarifying, yes we can turn the lights off on UK bikes.... I was wondering if I was going mad..
I had something similar in my imported Yamaha, "starter safety solenoid" or some other grand title. Took it all off and started again with that wiring!

People who have electronic speedo conversions, where did you take a permanent +12v from? I am a bit aprehensive of running another dedicated live direct from the battery (has 3 wires on the + terminal already). I would like to find a fused 12v somewhere, although looking at the wiring diagram I don't think I'll find one!

Sadly the body is 85mm, so the entire thing would not.
The internals are pretty much identical, bu the dial is bigger, if the dial could be turned down to 80mm then I believe the whole mechanism would fit into the ITI plastic case. The dials are not interchangeable because of where 0mph sits.
Here is a pic to show the Ducati gear you installed, the state of the old one, and the Ducati odo/trip gear and reset.

Dragging this up from the past, if anyone gets here looking for answers, the gear that sits on the worm drive, and also the connecting gear up to the odometer are identical in the Ducati ST2/ST4/900SS CEV speedo.
The face looks like this:
The trip button is also the same, so it's a good source of 3 spare parts!

Right, it's a tiny bit too big, so that's a no on direct fit.
But the mechanism is practically identical, so the gear that sits on the worm drive for the Speedo/trip is the same part, as is the connecting drive and Speedo reset knob.
So.... What is the best way to get the worm gear out? Bend the entire metal back plate down? Or is it better to try and go in from the front?
It doesn't look like the needle comes off? Are they glues/screwed on? Seems delicate.
Edit: prized the back plate down, put new worm gear in. Spent an hour tapping and bending the whole thing till the worm gear actually engaged.
Tip: do not bend the back down, figure out a way to remove the front!
Ducati ST2/ST4/900ss CEV Speedo gears do fit the ITI Speedo though, exactly the same, it looks like this:
I posted this on reply to a different thread, but here it is easier to find in case anyone needs it.

I put a tiny little rear light on the back, to replace the small, but crappy light/bracket arrangement that I was never happy with. This Shin-Yo light is supposed to be fender mounted on the top, but I took a gamble on it fitting/being visible under the V11 rear...

The thread on the gearbox that the angle drive attaches to is 16mm, but the clock side of the cable (on mine with ITIs ) is 12mm. Not sure if that is common...
I *think*. Those yellow bits are blanked off holes for lights, I have seen images on Google where they seem to have bulb holders in there.
EDIT: Bought one cheap just now, so we shall see! Nearly matches my mileage

Since I didn't get my arse in gear and finish wiring up my electronic speedo yet, but have manage to wrestle my bike into a working state and am now riding it, I find myself in need of something that has a working trip counter.
I have spotted a few 900ss Speedos on eBay, they are cheap and look kind of ok-ish.
Has anyone fitted one to replace an ITI Speedo?
Here is a Ducati item, the seller says the thread is "about 12mm" and has (badly) measured the diameter at 82mm.
Here is mine
Sorry for quality, I was showing the seller how to measure diameter!
So they look very similar. The Ducati item has fixed posts, but apart from that..what do we think??

I'm sure all these things are great, and I might sound like and stubborn old git (I'm actually 37, is there a youngest Guzzi rider trophy? ) but I have never had a problem with a loop of clear tube with one end in a glass bottle of old brake fluid; just pump out the old stuff and the air bubbles, it goes out into the bottle and the bubbles rise up, can't get sucked back in.

Just following up... I took my bike for it's MOT (uk annual test) today, not sure what I was expecting, but it feels like a new bike. The sheer amount of tinkering has (I think) beaten everything into submission.
No misfire on either cyclinder at idle
No hot idle cough or splutter
Smooth pull all the way to redline
Can hold at part throttle (anywhere) and it sits happily and smoothly
Drinks all the fuel....
So, all in all, doing all the tune up stuff, again and again until you get it right, makes a wonderful difference...
Had an entire family stop and marvel as I rolled past, kids shouting nice bike, I put this down to my wonderful rattle can paint job.....
